CONNECTING-BOX FOR BOILER-TUBES.

Specification of Letters Patent.

Patented Jan. 26, 1915.

Application filed June 18, 1914. Serial No. 845,876.

To all whom it may concern:

Be it known that I, CHARLES RADIGUER, citizen of the French Republic, residing at St-Denis, Department of the Seine, in France, have invented certain new and use ful Improvements in Connecting-Boxes for Boiler l ubes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The supply of water to boiler elements, and particularly to Belleville elements, may be facilitated if the water which supplies the lower tube instead of passing through a tortuous path is supplied parallel to the axis of the tube. Furthermore, this permits a quantity of water to be retained in the lower tube of the element in the case of a sudden cessation of the supply, and particularly in the case of an accident to a tube producing a leakage which tends to empty the boiler.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a vertical section of a lower connecting box taken on the axis of the lower tube of the element; and Fig. 2 is a section taken on the line XX of Fig. 1.

The lower box A is secured, by the hookended bolt 1, on the supply cone B, which in turn is connected with the collectorC. The sleeve D is secured in the box A in coaxial relation with the tube E. The said sleeve is preferably mounted by providing threads thereon and screwing the sleeve into the box, as shown in the drawing, or any other suitable means may be employed for the purpose, if so desired.

The sleeve D is provided with three open ings 2, 3 and 4, two of which are positioned at the bottom of the sleeve, and the third at the top of the sleeve, as clearly shown in Fig. 2. The sleeve D fits loosely in the tube E with a small amount of play, as shown at 5. The end of the sleeve adjacent the tube is formed with a partition 6, the top edge of which is slightly above the axis of the tube. Above the top edge of the partition, there is an opening 7, permitting water to be supplied from the box to the tube. The feed water, which is contained in the collector C, passes through the cone B, the box A, then through the openings 2 and 3 of the sleeve, and rises in said sleeve at the same time as in the box. The water flows over into the first tube E of the element as soon as it rises above the level of the top edge of the partition 6. The invention is applicable to the first tube of each of the coils of which the element may be composed.

In case there is a cessation in the supply of water, and particularly in the case of an accident to one of the tubes resulting in a leakage which tends to empty the boiler, the lower box may be emptied through the leak, owing to its communication with the collector, but the partition 6 will prevent the water contained in the lower tube from following that which is in the box. Time is thus obtained for making the necessary repairs before all of the water in the lower tube is vaporized, and the lower tube will, therefore, be protected against overheating or burning out.

What I claim is:-

l. The combination with a boiler tube and the box to which it is connected, of a perforated sleeve threaded in the box and coaxially disposed with respect to the tube, the end of the sleeve adjacent the tube fitting loosely therein.

2. The combination with a boiler tube and the box to which it is connected, of a perforated sleeve positioned in the box and co axially disposed with respect to the tube, said sleeve having a transverse partition to retain a quantity of water in the tube after discharge of the water from the box.

3. The combination with a boiler tube and the box to which it is connected, of means to retain a quantity of water in the tube after discharge of the water from the box.

4. The combination with a boiler tube, of a partition so disposed in the end thereof In testimony whereof I aflix my signature, in presence of two Witnesses.

CHARLES RADIGUER.

as to leave an opening between the tube and the top edge of the partition to permit Water to be supplied to the tube, said partition serving to retain a quantity of Water in the tube upon cessation of the supply of Water to the tube.
